The ancient Egyptians did not know the hard setting lime plaster invented by the Greeks, but used instead a mixture of gypsum and quartz with small amounts of lime [5] when working with stone.This was not as disastrous in the dry climate of Egypt as it would have been under wetter conditions.ost of the ancient Egyptian buildings have disappeared leaving no trace. Built of sun baked bricks made of Nile mud and straw, houses, palaces and city walls crumbled when they stopped being looked after.
In fact there were many cultures including Egyptians, Greeks and Romans that routinely used stitches or sutures in their medical treatment of wounds and surgical procedures. The first types of needles were primitive and were made of fine shards of bone or metals. This meant that the suture material tended to be coarser and heavier and was most likely originally made from plant materials. The first people to actually use surgical sutures are believed to the ancient Egyptians.
